ibdiagnet - IB diagnostic net
Synopsys
ibdiagnet [-c <count>] [-v] [-r] [-t <topo-file>] [-s <sys-name>] [-i <dev-index>] [-p <port-num>] [-o <out-dir>] [-lw <1x|4x|12x>] [-ls <2.5|5|10>] [-pm] [-pc] [-P << PM counter>=<Trash Limit>>]
Description
ibdiagnet scans the fabric using directed route packets and extracts all the available information regarding its connectivity and devices. It then produces the following files in the output directory (which defined by the -o option (see below)).
Files
ibdiagnet.log -
- A dump of all the application reports generate according to the provided flags
- ibdiagnet.lst -
- List of all the nodes, ports and links in the fabric
- ibdiagnet.fdbs -
- A dump of the unicast forwarding tables of the fabric switches
- ibdiagnet.mcfdbs -
- A dump of the multicast forwarding tables of the fabric switches
- ibdiagnet.masks -
- In case of duplicate port/node Guids, these file include the map between masked Guid and real Guids
- ibdiagnet.sm -
- List of all the SM (state and priority) in the fabric
- ibdiagnet.pm -
- A dump of the pm Counters values, of the fabric links
- In addition to generating the files above, the discovery phase also checks for duplicate node/port GUIDs in the IB fabric. If such an error
is detected, it is displayed on the standard output. After the discovery phase is completed, directed route packets are sent multiple times (according to the
-c option) to detect possible problematic paths on which packets may be lost. Such paths are explored, and a report of the suspected bad links is
displayed on the standard output.
After scanning the fabric, if the -r option is provided, a full report of the fabric qualities is displayed. This report includes:
- * SM report
- * Number of nodes and systems
- * Hop-count information
- * SM report
- maximal hop-count, an example path, and a hop-count histogram
- * All CA-to-CA paths traced
- * Credit loop report
- * mgid-mlid-HCAs matching table
- Note: In case the IB fabric includes only one CA , then CA-to-CA paths are not reported. Furthermore, if a topology file is provided, ibdiagnet uses the names defined in it for the output reports.
- * Credit loop report
Options
-c <count> :
- Min number of packets to be sent across each link (default = 10)
- -v :
- Enable verbose mode
- -r :
- Provides a report of the fabric qualities
- -t <topo-file> :
- Specifies the topology file name
- -s <sys-name> :
- Specifies the local system name. Meaningful only if a topology file is specified
- -i <dev-index> :
- Specifies the index of the device of the port used to connect to the IB fabric (in case of multiple devices on the local system)
- -p <port-num> :
- Specifies the local device's port num used to connect to the IB fabric
- -o <out-dir> :
- Specifies the directory where the output files will be placed (default = /tmp)
- -lw <1x|4x|12x> :
- Specifies the expected link width
- -ls <2.5|5|10> :
- Specifies the expected link speed
- -pm :
- Dump all the fabric links, pm Counters into ibdiagnet.pm
- -pc :
- Reset all the fabric links pmCounters
- -P <PM=<Trash>> :
- If any of the provided pm is greater then its provided value, print it to screen
- -h|--help :
- Prints the help page information
- -V|--version :
- Prints the version of the tool
- --vars :
- Prints the tool's environment variables and their values
